COIN-CONTROLLED APPARATUS- SPEGIFIGATION forming part of Letters I 'atent No. 760,502, dated May 24, 1904.

Application filed January 9 1904.

T0 aZZZ whom it ma concern;-

Be it known that I, ARTHUR E. WELLS, a citizen of the United States, residing at New York city, (Manhattan,) county and State of New York, have invented new and useful Improvements in Coin-Controlled Apparatus, of which the following is a specification.

This invention relates to a coin-controlled apparatus, such as a lung-tester, provided with improved means for preventing the machine from being worked by a succession of impulses.

In the. accompanying drawings, Figure 1 is a front elevation of a coin-controlled apparatus embodying my invention and showing the same applied to a lung-tester; Fig. 2, a side elevation, partly in section, of the coin-controlled mechanism; Fig. 3, a front elevation thereof; Fig. 4:, a view similar to Fig. 2, show ing the parts in a diiferent position; and Fig. 5, a detail of the mouth-tube and indicator.

The letter A represents the casing of the apparatus, within which is fitted a plate a, mounted upon a base a. To plate a is fulcrumed at b a beam Z), having at one end an inclined upwardly-extending projection Z) and asimilardownwardly-extending projection Z". At its other end the beam Z) is pivotally connected at c to a piston-rod c, the piston c of which plays in a cylinder (Z, open at its top. A pin 0 adapted to engage the upper end of cylinder (Z, limits the descent of the piston, while a spring 0 tends to draw the latter into Into the cylinder (Z enters an air-inlet tube f, having mouthpiece f, and an air-exit tube 9, which is adapted to convey the exhaled air to a suitable indicator. This indicator is shown to consist of a bell It, movable within a casing it, so that theheight to which the bell is raised will measure the volume of air admitted to the indicator.

At right angles to beam 6 there is fulcrumed to plate a at Z a coin-operated threearm lever I.- One arm c" of. lever I is arranged in the path of the coin B, which is introduced into a coin-chute A of easing A. After the coin has tilted the lever it clears the same and falls into asuitable receptacle. (Not shown.) The second arm i oiilever I is notched,

as at i to form a seat for beam 6, which is adapted to lock the beam in its normal position. The third arm 6* of lever I carries a weight j, which tends to raise lever-arm z" and to hold lever-arm Z against beam Z)- To a bearing a projecting forwardly from plate a, is secured a pivot it, upon which is adapted to swing a frame or yoke L. This yoke is composed of two inclined parallel bars Z, which are connected at or near their center by a tube Z, that embraces pivot The upper ends of bars Z are connected. by a crossarm Z located between the projections Z Z of beam Z). The lower ends of bars Zare disconnected from each other and carry each a counterweight m. To the tube Z of yoke L is rigidly secured a detent Z having a nose Z", which is by the weights at normally held against the front of lever I. When the lever I is tilted by a coin, the nose Z will pass underneath lever-arm 11*, and thus hold leverarm off beam Z).

The operation is as follows: Normally the piston c is in its lowermost position and intermediate the inlet and exit tubes f g, so as to cut off the former from the latter, Fig. 2. In this position the beam Z, and consequently the piston 0 is locked by the engagement of the beam with the notch 71 of lever-arm Z. Upon the introduction of a coin B into the coin-chute A the lever I is tilted so as to withdraw arm 71 from beam 6. (Dotted lines in Fig. 3.) As the lever I is thus tilted it will clear the nose Z of detent Z and will permit the weights on to, swing the yoke L with its upper end rearward. This movement of the yoke will cause the nose Z" to be projectcdunderneath lever-arm 2" and to thus lock the lever I in its tilted position. In this position the notch 41 of arm 7? is out of engagement with beam Z, so that the latter remains released. The tilting of yoke L will also have brought its cross-piece Z in engagement with projection Z) of beam 6, (full lines in Fig. 4,) by which means the play of detent Z Z is limited. Air may now be blown through tube the air raising piston 0 (dotted lines in Fig. 4,) so that communication is established between tubes f and g, and the exhaled air may operate the indicator. The raising of the piston 0 will effect a simultaneous tilting of beam 5 against the action of spring 0. As the beam is thus tilted, its projection F2 in descending will push the cross-piece Z forward to tilt the yoke L. (Dotted lines in Fig. 4.) In this way the nose Z* is Withdrawn from underneath lever I, and the latter is released. The weight j will consequently be free to tilt lever I and carry its arm 11 toward beam 6, so that the arm a will contact with the beam beneath its notch 2' The parts are brought into the above position at the beginning of the blowing operation and will be held in such posi tion while the exhalation continues. As soon, however, as the exhalation is discontinued or interrupted the spring 0 will tilt the beam 6 to lower piston c and cause the latter to assume its normal position intermediate the tubes f As the beam is tilted in the manner described its left end will be raised and carried opposite the notch i of lever-arm The weight j will therefore tilt the lever I and carry notch d underneath beam 6, so that the latter is relocked in position, Figs. 2 and 3. The locking of beam 6 will cause a simultaneous locking of piston 0 and thus the communication between tubes f and 9 remains inter rupted until the introduction of a new coin. It will be seen that immediately upon the cessation of pressure against the piston the latter will descend and be locked in this position to disconnect the inlet-tube from the indicator. Thus if the operator attempts to work the machine by two or more successive exhalations or impulses without the introduction of new coins such attempt will be frustrated.

What I claim is' 1. In a coin-controlled apparatus, the combination of a cylinder with an inclosed piston, a beam connected thereto, a coin-controlled lever engaging the same, and a pivoted frame having a nose adapted to be projected beneath the lever, substantially as specified.

2. In a coin-controlled apparatus, the combination of a cylinder with an inclosed piston, a beam connected thereto, a coin-controlled lever having a notched arm adapted to engage the beam, and a pivoted frame having a nose adapted to be projected beneath the lever, substantially as specified.

7 8. In a coin-controlled apparatus, the combination of a beam having an inclined projection with a coin-controlled lever having a notched arm adapted to engage the beam, and a pivoted frame having a cross-arm adapted to engage the inclined projection, and a nose adapted to be projected beneath the lever, substantially as specified.

a. In a coin-controlled apparatus, the combination of a beam having an inclined projection, with a weighted coin-controlled lever having a notched armadapted to engage the beam, and a weighted pivoted frame having a cross arm adapted to engage the inclined projection, and a nose adapted to be projected beneath the lever, substantially as specified.

5. In a coin-controlled apparatus, the combination of a cylinder with inlet and exit tubes communicating therewith, an inclosed piston, a beam connected thereto and having an inclined projection, acoin-controlled lever having a notched arm adapted to engage the beam, and a pivoted frame having a cross-arm adapted to engage the inclined projection, and a nose adapted to be projected beneath the lever, substantially as specified.
